Our next speaker is Raymund from Eurocom, presenting open-air interface. And I'm basically explaining why it's useful and relevant, what's coming in, why it's easy, and why you should care. Pretty much.
00:20
That's a tall one. No, I'll do my best. It's actually nice to come to this kind of event because I'm going to talk about my solution.
00:53
I'm going to try and talk a bit about my team, a bit about open-air interface, and also a little bit about I don't know whether or not
01:03
you guys are aware of 5G, but 5G is the evolution of the networks to support these things. And a lot of other things, aspects and skills to support this, examples to support all kinds of things. And I'd love to hear from you.
01:20
A lot of people also talk about the new air that this new data is. For me, it's a lot more than that. It's also the evolution of the way that we can utilize the execution of the information that's out there.
01:43
We're very familiar with the central offices.
02:04
The other aspect that's coming now is starting with 4G. High performance of our front home.
02:23
And basically, this is a very advanced fix network to support it. We're talking about wireless communication, but actually, the fix network supports wireless communications. And it's also going to be much more centralized
02:40
as it continues in storage. On a much more general purpose, there's a lot more Intel servers that are running a data interface. And more and more software technologies that are coming into play. And all of this is going to be combined
03:01
with radar signal processing. And someone talked to me about the real-time issues in the switching room. We're also working on issues in the signal processing. This is all coming together in these new law-based units together.
03:21
People are talking about all of this in the context of 5G, but actually, this is also happening. At the same time, a little bit about the source. What's happening is because of this merge of the information technologies and the cloud computing,
03:45
there's a lot of stuff going on now in the telecommunication. So what are we going to do about this? Just to give you an example, there's a focus group by the IT team which was there to study the fix-line
04:00
of wireless devices. Fix-line of wireless devices. Can you explain to them? One of their objectives was to reach out to the open source community preparing the scene of the class
04:22
between the basic students and the three people together to talk to us and give us a place
04:42
to actually adapt to everything. And then there was one other community that I had to do the open source and the standards for 5G.
05:00
This is the first time I saw 5G together with Open Source. And what was very interesting is the place where the company
05:22
when it comes to wireless community is held to talk about standardization in the open source environment. So you have the ones that are four. So there were a lot of technical discussions there
05:41
how the telecommunication community should be working with Open Source and where Open Source is at with the technical department in the morning. The non-technical department are Open Source and the standards are even compatible at all. Should Open Source licenses be predefined or left open to the organizations?
06:02
What's more efficient, Open Source in fact, Google licenses and what are the threats to many different databases? This was a very different situation. Actually, it was actually for me, it was a positive outcome.
06:21
From my perspective, when we were developing Open Source software we were able to do a serious calculation and basically
06:44
it's a question of the license and the community. If you want to have people like welcome and make up their access in the community, the licenses have to be adapted so they can still benefit
07:02
from their investments and quite frankly there's a question of the license
07:20
that's the issue here with the organization bodies there are other solutions as you can see there's a lot of smaller players and there's some very old statements
07:40
there's a small company in UK called Lanark it's a small company it's a small company their chips could be used in small base stations on the private good R&D they're working economically to try and push Open Source right down to the very base they're talking to operators in the UK
08:03
about using open source in the UK that's a pretty bad idea another evolution are new players in this game and there are two big new players
08:20
in the UK if you've ever looked at this project suggest you take a look at that project it's a very powerful company
08:49
this is going to change first here
10:47
this is what the network is going to look like
11:15
what's very interesting is those are all of the controllers which are a monster network
11:24
and allocating between the different servers and different slices this is going to be very
11:53
what I think all of these is that at least
12:00
the control framework all of those boxes that's most of the focus
12:28
this shows you the different types of radio systems the one at the top is an indoor network places where everything is extremely important
12:45
what you see here is basically this is the central office engine of the cloud center which is basically and then in each one of these remote radio systems
13:04
this is called a radio aggregation unit which is a physical device which is there to interconnect all of the remote radio units so you have them on the inside you have them in the outdoor and you also might have some small cells
13:21
that are interconnecting this unit here is going to be the joint processing of all of these and then access the gateway to the protocol network the other region
13:55
the other region is the one the protocol stack
14:04
this is where it's going to work when it comes to the real thing some of these functions here are going to be virtualized
14:20
so you're going to have different types of so-called frontal networks the low latency frontal networks and the high latency frontal networks and that just refers to how much of the physical layer is far away so this could be for instance a low latency frontal network which is a 10 kilometer relief
14:41
and the physical layer is actually only needed to know about that or you could have higher latency frontal splits where the radio nodes themselves have more of the layers
15:00
but all of these things will exist you will have some radio nodes that have almost no physical activity and others that will have all of it you will also have some that are even dedicated to the internet and wifi to this data platform
15:20
so is it going to be better if you need to do that all of these boxes could potentially
15:40
could potentially be virtualized and that's also what's going to be used to study data and what it's going to be used for me, I'm not actually
16:03
rolling this out I can see the benefits and customize your network much more than you think you're also going to be able to tailor if an operator wants to move forward
16:25
if an operator wants to benefit which is run by the other main thing is the stuff we're running in terms of challenges
16:46
for me, it's the real time processing but in 4G basically you need to have reactivity of a millisecond you have to be able to stimulate a millisecond
17:00
and that is a hard way to run you can have a little bit of jitter and 100% jitter is okay but still you have that 5G is going to be too in terms of real time
17:21
the other issue for me in terms of challenges
17:41
for 4G I think we've already seen that SDM concepts are going much deeper you're going to start to do SDM very finely very controlled so I'm talking about the max schedules
18:02
this is how I'm keeping up on the scheduling policy managing dynamically at the moment basically the notion of a base case is a virtual one you have a lesser than that and you trick the terminals actually to a base case
18:21
that kind of thing requires definitely running multiple if you want to mix 4G, 5G Wi-Fi on the same
18:41
having multiple operators sharing the same hardware and also if you want to mix private and public traffic
19:01
these are definitely good challenges another one that real time
19:30
processing I think when it comes to 5G we're going to start I think
19:47
fancy
20:24
robust so even on the latest the latest the deadline schedulers
20:47
more recent and what's actually 14.1 today is usually
21:00
there are other people that don't discuss
21:50
primarily
22:46
I'm experimenting with SDM it's already happened traditional platform operators are starting to play I didn't talk that much about
23:02
the hardware that's something there are already players
23:21
who are going to change the way this all happens definitely more personal benefit from the conference course and have an impact on
23:40
on the systems 4G has very I would encourage people to work with open source like myself if you have a big hardware and that you
24:02
we're putting together a mock network that reflects that people could in principle deploy a small network control 15 to 100 data nodes and give a memory for them
24:23
we are very very it's very easy
24:47
essentially set up projects they're very keen on the way
25:31
the way of the
27:19
the way of the
